Abstract

In this experimental investigation, the effect of concentration, size, and temperature on the viscosity of Al2O3-water nanofluid has been studied. The experiments performed on the various concentration of Al2O3 -water nanofluid with particle size 13 nm, 50 nm and 150 nm in the temperature range of 25-80 ℃. The viscosity data were collected using stress-controlled Bohlin Gemini rheometer. The effect of pH value on the viscosity has also been studied. Exponentially decrease in viscosity with an increase in temperature was observed. It has been analyzed and found that the viscosity decreases with temperature and follow the same pattern of decrement for all concentration and size of nanofluid. Al2O3-water nanofluid has been found Newtonian behavior for 50 nm and 150 nm particle size samples at the ambient temperature in the shear rate range 100 s-1 to 250 s-1.

Keywords: Nanofluid, Suspension, Dynamic Viscosity, Concentration, TEM, FESEM
